CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. § 119(e) to U.S.Provisional Patent Application Ser. No. 62/810,079, filed Feb. 25, 2019,the entire contents of which are incorporated herein by reference.

FIELD

The present invention relates to the field of therapeutic treatments andcompositions for skincare, including skincare treatments andformulations for application to the skin, for example, in combinationwith any skincare treatment or regimen at-home or professionallyadministered, including before and/or after dermatological proceduresthat affect, for example, disrupt, the skin's barrier to alleviatediscomfort and enable healing of the skin and to improve treatmentoutcomes, as well as to methods for their application to the skin,formulation, manufacture and use thereof.

BACKGROUND

Various dermatological procedures, such as microneedling, RFmicroneedling, laser, chemical peels, intense light therapy,microdermabrasion or dermaplaning, are used to treat and improveconditions like acne scarring, fine lines and wrinkles, loose skin, skintexture, pore size, brown spots, stretch marks, and pigment issues. Suchprocedures tend to disrupt the skin's barrier and/or cause redness,irritation, inflammation, among other skin conditions, which need to beaddressed and corrected. For example, in microneedling procedures themicroneedling depth is enough to draw blood and to irritate and/orinflame the skin, which could require healing.

Other anti-aging and corrective skin procedures can involve chemical,thermal and mechanical wounds. Patients having such treatments haveextremely irritated and sensitive skin after the treatment requiringfurther post-procedure treatments with, for example, cold compresses,wet soaks or occlusive ointments. However, some such post-treatments maycause further irritation and inflammation, rather than alleviate thepost-procedure condition being treated.

Mask sheets are used in skincare and are shaped to be attached to, forexample, the face. Such masks are used for burn treatment, skinmoisturizing, skin whitening or skin nutrition, and are made ofnon-woven fabrics, such as vegetable cellulose fibers, i.e., cotton orpulp, or of synthetic fibers. Some such sheets have been foundproblematic since the sheets dry within a short period of time afterapplication and foreign materials, such as dust, may also get attachedto the skin along with the mask sheets. Bio-cellulose mask sheetssaturated with water also are used for applying to the skin.

The prior methods, formulations, and delivery systems, however, do notprovide efficacious and fast acting pain and swelling relief, orimproved treatment outcomes from the applied dermatological procedures.Typically, such do not prevent discomfort and inflammation, and are noteffective in rapid healing of the skin conditions described above thatoccur, for example, in situations of dermatological procedures affectingthe skin's barrier.

Accordingly, there is a need in the art for improved methods,formulations and delivery systems thereof that can provide treatment tothe skin of those in need thereof to alleviate and ameliorate one ormore of the conditions noted above. More specifically, there is a needin the art for improved skincare formulations and methods to treatredness, irritation, inflammation, among other skin conditions, and toimprove treatment outcomes in dermatological office procedures, byutilizing such formulations and methods either before or afterdermatological procedures, such as microneedling, laser, chemical peels,intense light therapy, microdermabrasion or dermaplaning, that causedisruption, irritation and/or inflammation of the skin, and with otheranti-aging and corrective skin procedures that can involve chemical,thermal and mechanical irritation and wounds to the skin.

The methods and systems disclosed herein are designed to provide coolingand soothing features to sooth, calm, reduce redness, swelling andburning sensations, and prevent inflammation and promote healing moreeffectively than prior topical formulations and systems.

DETAILED DESCRIPTION

The present disclosure provides skincare formulations, delivery systems,and methods of use thereof for alleviation or amelioration ofdermatological conditions relating to dermatological procedures thatirritate and/or wound human skin. Dermatological conditions amenable totreatments disclosed herein include, without limitation, inflammatorydisorders of the skin and skin conditions characterized by increasedcell turnover including psoriasis, photoaging, weather-beatenappearance, yellowing, loss of elasticity, loss of collagen richappearance and/or youthfulness, redness, dryness, age spots, skinwrinkles, acne, rosacea, ichthyosis. The disclosed therapeuticformulations are also useful for improvement in one or more aestheticcriteria, including, but not limited to, a perceived improvement inapparent skin age, skin tone, weather-beaten appearance, yellowing, lossof elasticity, redness, dryness, age spots, skin wrinkles, skinsmoothness, brightness, radiance, as well as skin pores becoming lessnoticeable.

As used herein, the terms “treatment” or “treating” with respect to askin condition generally mean “having positive effect on a skincondition” and encompass reduction, amelioration, and/or alleviation ofat least one symptom of a skin condition, a reduction, amelioration,and/or alleviation in the severity of the skin conditions, or delay,prevention, or inhibition of the progression of the skin condition.Treatment, as used herein, therefore does not require total curing ofthe condition. A formulation of the present disclosure that is usefulfor treatment of a skin condition, or a method of treating a skincondition, need only reduce the severity of a skin condition, reduce theseverity of symptoms associated therewith, provide improvement to apatient's quality of life, or delay, prevent, or inhibit the onset ofone or more symptoms of a skin condition. As used herein, these termsalso encompass aesthetic improvements to the skin upon application ofthe disclosed formulations having a combination of, for example, anoligopeptide, antioxidants, and hyaluronic acid or its derivatives .

As used herein, the terms “application,” “apply,” and “applying” withrespect to a disclosed topical formulation or method of using adisclosed topical formulation, refer to any manner of administering atopical formulation to the skin of a patient which, in medical orcosmetology practice, delivers the formulation to the patient's skinsurface. Smearing, rubbing, spreading, spraying a disclosed topicalformulation, with or without the aid of suitable devices, on a patient'sskin are all included within the scope of the term “application,” asused herein. The term “topical” or “topically” with respect toadministration or application of a disclosed skincare formulation refersto epicutaneous administration or application, onto skin.

The present disclosure further contemplates administration orapplication of the disclosed skincare formulations using a sheet-likestructure, such as a mask configured for attachment to a desired area.In particular, the present disclosure contemplates use of applicatorsystems, such as biocellulose face masks, which are surprisinglyeffective in providing therapeutic treatments with the disclosedformulations.

A biocellulose mask is a device, generally supplied as a sheet, eitherindividual or multiple quantities per package, which may be pre-cut toconform more easily to a particular body area or, for example, containcut-out areas for eyes, nose, mouth, or perhaps have cuts or wedgesremoved in order to facilitate better adhesion to the skin when wet withwater or a treatment solution.

The present disclosure contemplates any suitable biocellulose materialfor the types of masks disclosed herein. In this, a person skilled inthe art would be familiar with such materials and masks thereof.Biocellulose fibers are hydrophilic and hold water and hydrophilicsolutions very efficiently. They conform well to the skin providing anefficient diffusion gradient, with beneficial ingredients entering theskin and having the potential to absorb unwanted allergens or chemicalsfrom the skin. The moisture trapping ability allows the mask toevaporate water at a high rate, causing continued cooling over longperiods of time, even when applied to warm skin. This provides coolingcomfort and reduction of redness, swelling and other complications afterlaser or other treatments which may disrupt the skin's barrier, viaphysical, thermal, chemical or other types of wounding. Further, thisprovides effective treatment and healing of such types of skin barrierwounding.

Biocellulose fibers and sheet goods may be easily sterilized by heat,chemical, radiation, or other methods. They are largely inert and do notirritate or exacerbate skin injury during treatment. They transmitactive ingredients efficiently and hold them in stable formulation overa reasonable shelf life.

The present disclosure further contemplates the use of masks of anysubstrate material that is suitable for the purposes and resultsdiscussed herein.

As used herein, the phrase “effective amount” refers to an amount of aformulation of the present disclosure, or component thereof, effectiveto treat a skin condition as noted above, including a range of effects,from a detectable local improvement in an area of topical application tosubstantial relief of symptoms to an improvement in one or moreaesthetic criteria, including, but not limited to, a perceivedimprovement in apparent skin dryness, keratosis pilaris, age, radiationdamage, sun or uv damage, skin tone, weather-beaten appearance,yellowing, loss of elasticity, redness, dryness, age spots, skinwrinkles, skin smoothness, brightness, radiance, as well as skin poresbecoming less noticeable. The effective amount will vary with theparticular condition or conditions being treated, the severity of thecondition, the duration of the treatment, the specific components of thecomposition being used, and other factors. More specifically, thedisclosed compositions and formulations provide a method for therapeutictreatment of skin by providing, in some embodiments, a combination of anoligopeptide and an antioxidant, in an efficacious manner to the skin.

The disclosed compositions, formulations and methods of use thereofreduce, minimize, or eliminate normally-observed dry skin conditionsincluding, inter alia, conditions characterized by redness, swelling,itching, severe skin flaking, breakdown of the skin barrier, discomfort,extreme dryness, cracking of the skin, burning sensation andsensitization. The disclosed compositions, formulations, and methods ofuse thereof also provide aesthetic improvements in the skin, including,but not limited to, skin that appears younger, skin exhibiting a moreeven tone, skin in which the pores are less noticeable, and skin that isjudged by the user to be smoother, and/or to be improved with respect toits weather-beaten or aged appearance, yellowing, loss of elasticity,redness, dryness, age spots, and/or skin wrinkles and scarring, forexample, acne scarring and other pitted lesions and melasma or otherskin pigmentation issues immediately after medical or aestheticprocedures to the skin and for a length of time thereafter where thesubject may feel discomfort or dryness of any kind.

As used herein, the phrase “skin barrier” refers to the outermost layerof the skin's surface. As is generally known, the skin barrier has cellsand lipids, and may also be referred to as the permeability barrier,moisture barrier, or lipid barrier. The skin barrier preventsevaporation of essential water and electrolytes from the skin, amongother functions. As disclosed herein, various processes may disrupt,i.e., weaken or affect, the skin barrier causing, among others, pain,swelling, redness, dryness, irritation, susceptibility to infection,which require healing and repair. The extent of skin barrier disruptionmay vary based on the specific dermatological procedure from minorpenetration to depths that draw blood to the skin surface. For example,microneedling procedures may be adjusted for depths of penetration basedon the skin conditions under treatment. Various dermatologicalprocedures are used for promoting collagen production to treat skinconditions.

As used herein, the phrase “dermatological procedure” refers tosurgical, medical, or simple procedures, for example, rendered by aphysician, esthetician, skincare service provider, or end-user at home.For example, at home daily, simple cleansing and moisturizing routines,such as treating a person's simple dry skin condition, affecting theskin barrier, are within the scope of the phrase “dermatologicalprocedure.”

As used herein, the terms “masks” or “mask sheets” refer to shaped orunshaped sheet-like structures that are used in skincare and may beshaped to be attached to, for example, the face. Such sheets are usedfor burn treatment, skin moisturizing, skin whitening or skin nutrition,and are made of non-woven fabrics, such as vegetable cellulose fibers,i.e., cotton or pulp, or of synthetic fibers. In certain embodimentsherein, biocellulose sheets saturated with formulations disclosed hereinmay be used for effectively delivering active agents to the skin and forprotecting and soothing the skin barrier.

As used herein, the term “on an active basis” refers to the actualpercentage or composition of an active ingredient, such as a peptide, asused in a formulation.

Sheets may be used, for example, for facial masks, adhesive skinpatches, or the like, used for facial treatment, skin treatment, or thelike, including delivery systems, i.e., carriers, of active ingredientssuch as skin healing/repair components, and the like. These sheets areadhered to the skin to impart active components contained in the sheetsto the skin surface. In addition, when a sheet contains various activeingredients and is tightly adhered to the skin, the sheet providesfunctions, such as controlling skin temperature, water retention and/orsupplying the active ingredients in the sheet to the skin. Inparticular, when a sheet having a liquid component is adhered to theskin and kept in place for some time, physiology of the skin can beimproved owing to, for example, favorable moisture content ortemperature. Such functionality of the systems disclosed herein havesurprisingly been found to improve penetration of active agents into theskin thereby enabling rapid healing and relief from irritation andredness.

In addition to the foregoing, the present disclosure contemplates use ofadditional methods of applying the disclosed formulations including, butnot limited to, spray aerosol, cotton pads and balls, gauze, foam,tissue applicators, human hands, among others.

The skincare compositions and delivery systems disclosed herein not onlymaintain the active properties of the active agents, but also providegreater efficiency of the active agents. In one aspect of thisdisclosure the skin is human skin. In other aspects of the presentdisclosure, the skin is that of a companion animal, a domestic animal,or a commercially useful animal.

EXAMPLE

Dermatologic procedures may be accompanied by slow healing andpost-treatment discomfort. Biocellulose masks according to the presentdisclosure are designed to, for example, relieve post-procedurediscomfort, improve rates of healing, and reduce the appearance ofredness, among other beneficial results disclosed herein.

The following study was carried out to evaluate the efficacy and safetyof a sterile, treatment-formulation infused, biocellulose mask accordingto the present disclosure to accelerate healing, enhance improvement,and reduce post-procedure discomfort following a RF/microneedlingtreatment of the face.

Ten healthy females aged 35 to 60 years, moderate wrinkles, enrolled inthe open-label, single-site pilot study. Subjects were treated once with2 passes of a microneedle radio-frequency (RF) device. Treatment wasimmediately followed by application of a biocellulose mask according tothe present disclosure to the entire face for 15 to 20 minutes. Subjectswere given an additional six masks for daily home use and asked toreturn to the office 3 and 7 days later for evaluation of efficacy andsafety. Skin responses were tracked by photography of subjects' facesimmediately post-procedure (pre- and post-mask application), and on days3 and 7. Clinical grading was performed.

Subjects achieved statistically significant improvement in skinradiance, smoothness, texture, and dryness after a singleRF/microneedling treatment followed by daily usage of the biocellulosemask for 1 week. Skin tone evenness, red/blotchiness, and overallappearance were trending toward significant improvement by Day 7.Adverse events were not observed in any subject.

The results demonstrate the effectiveness of the disclosed biocellulosemasks pre-moistened with the disclosed formulations in soothing skin andaccelerating its healing post a RF/microneedling procedure. The masksand formulations according to the present disclosure may be useddirectly on compromised skin immediately post-microneedling, without anyadverse events. Improvement and conditioning of the facial skin usingthe disclosed masks daily for one week after treatment has been shown.
